He played 56 minutes before being replaced by Júnior Negrão, and his side eventually suffered a 2–0 away loss. After playing his first AFC Champions League match as a 70th-minute substitute in a 2–2 away draw with Kawasaki Frontale on 18 April, he appeared as a substitute in two more K League 1 matches against Suwon Samsung Bluewings and Pohang Steelers in May.

Loan to Asan Mugunghwa

On 24 January 2019, Oh moved on loan to K League 2 club Asan Mugunghwa, whose status was going to be changed from the police's club to a city-owned club due to a plan to abolish the auxiliary police in South Korea. On 2 March, he made his Asan debut and first professional goal in a 3–0 away win over Jeonnam Dragons. He got more opportunities at the new club, scoring seven goals in 30 K League 2 matches.

Oh started to represent South Korea at the 2015 FIFA U-17 World Cup. Under manager Choi Jin-cheul, he played four matches as a substitute until the round of 16, where South Korea lost 2–0 to Belgium, and scored the winning goal in a 1–0 win over Guinea. By manager Chung Jung-yong, Oh was called up to the South Korea under-20 team for the 2018 Toulon Tournament and the 2018 AFC U-19 Championship. He played only two matches as a starter at the latter, where his country qualified for the 2019 FIFA U-20 World Cup as runners-up. At the U-20 World Cup, however, he became their main striker, playing all seven matches until the final including six as a starter. Before South Korea lost to Ukraine in the final, he scored each of two headers against Argentina and Japan, and scored his team's last penalty in a penalty shoot-out win over Senegal. Oh was selected for the South Korea under-23 team for the 2020 AFC U-23 Championship by manager Kim Hak-bum. He scored a brace in their 2–1 win over Uzbekistan. After getting involved in Taeguk Warriors' first victory at the competition and qualification for the 2020 Summer Olympics, he was selected for the Team of the Tournament by Fox Sports Asia. On 6 June 2024, Oh made his senior international debut as a 87th-minute substitute for Son Heung-min in a FIFA World Cup qualifier against Singapore, which ended in a 7–0 win. On 15 October, he scored his first international goal in a World Cup qualifier against Iraq, where South Korea won 3–2.

Oh is a center-forward, who performs the role of target man. Noted for his physique and aerial ability, he is frequently compared with Kim Shin-wook, another South Korean international and his role model.
